I know there has been a similar discussion about 80287's, but I
need related info on the 8087:

I have an XT with a V20 processor running at 8/4.77Mtz.  What speed
coprocessor do I need.  If there are different speed 8087s, can I
use a 4.77Mtz 8087 and set the system speed to 4.77?  What if I run
the system at 8Mtz with a 4.77Mtz 8087?  Will it work?  Will it
overheat?

Thanx in advance!
